Ответ:
2/3 X 7 + 5/7 X 3
When we do that, we get 14/21 + 15/21
So when we add, the answer is
29/21
When we look at that, we have to see if it can be reduced. We know that both 7 and 3 can go into 21 but can they go into 29? No, so therefore, the answer cannot be reduced
Final answer is 29/21
Ответ:
2 × 7 + 5 × 3
3 × 7 + 7 × 3
Then rewriting the equation with the equivalent fractions
__14__ 15
= +
__21 __21
With like denominators we can operate on just the numerators
__14 + 15
=
___21
__29
=
__21
Simplifying the answer
__29
=
__21
___8
= 1
___21
