Find the difference between 7 1/2 and 2 3/4

NNADVOKAT [17]

Answer:

4 $\frac{3}{4}$ or 4.75

Step-by-step explanation:

first we're going to convert the number into improper fractions.

7 $\frac{1}{2}$ = $\frac{15}{2}$ and 2 $\frac{3}{4}$ = $\frac{11}{4}$

For subtracting it is suitable to adjust both fractions to an equal denominator, so we're going to multiply $\frac{15}{2}$ x2, it'll equal the same number.

So now we have $\frac{30}{4}$ - $\frac{11}{4}$ , 30-11= 19.
