Answer 2

$\dfrac{3}{4} \times\ 38$

38 is equal to 38/1. So the fractions can be written as follows.
$\dfrac{3}{4} \times\ \dfrac{38}{1}$

In a fraction multiplication, we operate them by multiplying the numerator to the other numerator and multiplying the denominator to the other denominator. Or we could write it like this.
$\dfrac{3}{4} \times\ \dfrac{38}{1}$
= $\dfrac{3\times\ 38}{4\times\ 1}$
= $\dfrac{114}{4}$

Because the numerator and the denominator are divisible by 2, we should simplify the fraction form
= $\dfrac{114:2}{4:2}$
= $\dfrac{57}{2}$

break 57 into (56+1)
= $\dfrac{56}{2}+ \dfrac{1}{2}$
= $28+ \dfrac{1}{2}$
= $28 \frac{1}{2}$
= 28.5
