Question

I badly want the answer to these☠️​

Answer 1

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