Answer: 1/5+1/2, 3/10+2/5
Step-by-step explanation:
We can describe the sum of fraction by taking below examples.
Let there are two friends and someone gave them some money
let one friend got 1/5 of the total money while second one get 1/2 of total money.
Then, total part of money gave by their friend = 1/5+ 1/2 =7/10
Let us take another example, if I have a bread and I have eaten 3/10 part of the bread while I gave 2/5 part of the bread to my friend then total utilized part of the bread = 3/10+2/5=7/10
