Which on is bigger 7/8 or 5/6

Nope - 7/8 is greater Here's a cool way to solve these types of problems First write 5/6ths and 7/8ths on a sheet of paper. Then multiply the numbers that are across from each other. 8x5 and 7x6 are the numbers. 8x5=40 7x6=42 42 is greater than 40, and the numerator of the fraction used in the equation is the bigger fraction. 7 is the numerator of 7/8 which is bigger than 5/6.
