algol13

<u>Answer:</u>

11

<u>Step-by-step explanation:</u>

We are given the following expression and we are to solve it:

\frac {70} {14} + \frac {54} {9}

Simplifying both the fractions before adding them to make it easier to solve:

= \frac {70} {14} + \frac {54} {9}

= 5 + 6

= 11

Therefore, the answer to the given mathematical expression is 11.
