Okay so for this, visualize the blocks are stacked on top of each other. Each block is 3/4 of an inch thick so all you have to is multiply 3/4 by 12. So:
\(\frac{3}{4}\) × \(\frac{12}{1}\) = \(\frac{36}{4}\)
However, the fraction 36/4 is not in lowest terms, so we need to reduce it. List the factors of the numerator and denominator:
Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36
Factors of 4: 1, 2, 4
4 is the largest factor of both 36 and 4, so we need to divide both the numerator and denominator by 4.
Numerator: 36 ÷ 4 = 9
Denominator: 4 ÷ 4 = 1
Write the new fraction: 9/1 = 9
So this is FALSE.
Hope this helps :)
