Question

Whats the answer I am stuck

Answer 1

15/28 I believe is the answer

Answer 2

Answer:

3 $\frac{11}{28}$

Step-by-step explanation:

Note that

2 $\frac{1}{7}$ = 2 + $\frac{1}{7}$ and

1 $\frac{1}{4}$ = 1 + $\frac{1}{4}$

We can add the whole numbers together and the 2 fractions separately, that is

2 + 1 + $\frac{1}{7}$ + $\frac{1}{4}$

To add the fractions we require them to have a common denominator

The lowest common multiple of 7 and 4 is 28.

Multiply the numerator/denominator of the first fraction by 4

Multiply the numerator/denominator of the second fraction by 7

= 3 + $\frac{1(4)}{7(4)}$ + $\frac{1(7)}{4(7)}$

= 3 + $\frac{4}{28}$ + $\frac{7}{28}$

= 3 + $\frac{4+7}{28}$

= 3 + $\frac{11}{28}$

= 3 $\frac{11}{28}$
