Answer:
9/10
Step-by-step explanation:
you find the lowest common denominator in this case is 10
then you take 1/2 and multiply it by 5 both the bottom and top and then you should get 5/10
next you do the same with 2/5 but this time to the get the denominator to 10 you multiply by 2 again multiply both bottom and top and you should get 4/10
now you just add 4/10 and 5/10 together and you get 9/10 or 0.9 as a decimal
-1.0, -3/4, 0.25, 3/2
hope this helps :D
Answer:
48/7

3 1/5 . 2 1/7
= 16/5 * 15/7
= 16/1 * 3/7
= 48/7
When rounding to the nearest whole number from 119.63 you need to round the number up as the tenths column is above 5 meaning that the answer is 120 :)
