Question 1184393
length of the pipe is 2 + 1/4 meters = 9/4 meters.
he uses 2/3 of that.
he has 1.3 of that left = 1/3 * 9/4 = 9/12.
he uses 1/8 of that.
he has 7/8 of that left = (7 * 9) / (12 * 8) = 7/8 * 9/12 = 7/8 * 3/4 = 21/32.
he cuts that in half to get 21/64 meters length for each of the remaining pieces.
that's your solution, if i did this correctly.
i did doublecheck with a calculator and it looks good.
