Answer:
Step-by-step explanation:
Let the number = x.
We are trying to find out what number (x) we would need to add to 7/12 to get 4/15

Subtract 7/12 from both sides.
We need to make the denominators of the fractions the same.


So,

The answer is 36/49.
You take the second fraction and flip it (it will be 12/14) and you multiply straight across. You get 72/98. You simplify it by finding it's greatest common factor (in this case it is 2) so you divide it the numerator and the denominator by 2. You get 36/49.

Answer:
what is the expression? please provide an expression.
<span>The number can be 102, 108, or 114. They can all be formed that way.
32 + 34 + 36 = 102
34 + 36 + 38 = 108
36 + 38 + 40 = 114
</span>The n<span>ext one is 120 . . . . . 38 + 40 + 42</span>
