Vedmedyk [2.9K]2 years ago
5 0

Step-by-step explanation:

1. 4/10 + 15/10

The two fractions have like denominators so you can add the numerators.

Then:

4+15/10=19/10

This fraction cannot be reduced.

The fraction

19/10

is the same as

19÷10

Convert to a mixed number using

long division for 19 ÷ 10 = 1R9, so

19/10=19/10

Therefore:

4/10+15/10=1 9/10

2. 50/20+60/20=5 1/2

3. \sf \frac{60}{40}  +  \frac{80}{40} = 3 \frac{1}{2}

4. \sf\frac{90}{60}  +  \frac{80}{60} = 2 \frac{5}{6}

5. \sf \frac{120}{40}  +  \frac{80}{40} = 5

6. \sf \frac{120}{40}  +  \frac{140}{40} = 6 \frac{1}{2}

7. \sf \frac{110}{70}  +  \frac{40}{70} = 2 \frac{1}{7}

8. \sf \frac{45}{5}  +  \frac{60}{5} = 21
