I am not sure what you are asking

So there is 8,8th in an inch and if you get something like 10/8 it doesn’t work because there is no 10 over 8 on the tape measure so you subtract 8 from 10 and that’s how he got 2/8 but the 4 he just added 1 to 3 and I’m guessing if you ever get a number that goes over an 8th or a 16th you’d take the inch and add 1 I’m not sure about that part

Dylan - Good explanation. What Joe was talking about was simplifying the fraction of 3 10/8 - that is considered an improper fraction and it is equal to 4 1/8. If you have 10 8th's that is the same as saying 1 whole and 2 8th's

You would calculate the surface area of the proposed wall (Length X height) and divide that number by surface area of the block.

@@ConstructionEd say the wall is 14×8,and a block is 8" high and 16" in length,how you calculate to get the amount of blocks for that side of wall . thanks in advance

First determine the area of the wall multiply the 14' by the 8' that equals 112 sqft Then calculate the area of the blocks blocks - 8'' x 16'' equals 128 sq inches and that converts to 0.888 square feet per block. so then divide the wall area by the blocks area and you get teh number of blcoks = 112 sqft divided by 0.888 sqft equals 126 blocks But remember to account for the mortar joints also.

@@ConstructionEd sir im very bad a math like this do you think I can do framing/construction

That is hard to do in a comment thread. But, when you subtract 7/8th you can think of it as two steps. First remove the 5/8 and you are left with 92. But you still have to remove the remaining 2/8th. Since 92 is the same as 91 8/8th, you can remove the final 2/8th and you are left with 91 6/8

Make sure you find the LCD and get the fractions to match, in this case 5/8 and 7/8 are already setup. Next subtract 5-7, which gives you -2. So now you have a fraction that's -2/8 which can be simplified as -1/4. Now you can't have a negative fraction so take that negative away by subtracting 1 from 92 which leaves you with 91. Now you have that 1/4 which used to be negative, so flip it to 3/4. Don't question it lol. You can apply this to say, 92 5/8 - 6/8 -> LCD is good, subtract 5-6, which is -1. You're left with -1/8. Get rid of the negative by subtracting 1 from 92. Then flip the 1/8 to 7/8. The answer would be 91 7/8" Let's say you have 92 5/8" - 91 7/8". First subtract the whole numbers, 92 - 91 = 1. Next check the LCD for the fractions, they are already good. Now to the same as before, 5-7 = -2 so you have -2/8 or -1/4 simplified. Get rid of the negative by subtracting 1 from our whole number, which would be 1 - 1 = 0, then we flip the fraction from 1/4 to 3/4 since we removed the negative. So the answer to this would be we're left with 3/4" after our cut. Kind of a weird cut IMO LOL.

Sorry, those resources are part of our teacher resources

You can pull 16 out of 21 once which equals and inch and you are left with 5/16

Brian, 1/2 is equal to 8/16. If you divide 8 into the top (numerator) it is 1 and if you do the same to the bottom (denominator) it is 2. so that is 1/2. You can also search for the term simplifying fractions, there are a bunch of good youtube videos about it.

@@ConstructionEd thank I'm very new student of trade in Construction I want to learn the very bottom basics
