Kevin and Tiana are making soup. The recipe calls for a pound of onions. They have one onion that weighs ½ pound and another that weighs ⅖ pound. Kevin says they only have 3/7 pound of onions, so they definitely don’t have enough. Why is Kevin wrong?
PLSSSS HELP!

Sagot :

Kevin is wrong because adding fractions, you don’t add the numerator and the denominator on each one like you do when you are multiplying them, instead you have to find a common denominator, which is the lowest number that is a multiple of all of your denominators so in this case tej common denominator would be 10, so on the 2/5 fraction times the top and bottom by 2 so you get 4/10 and on the 1/2 fraction times the top and bottom by 5 to get 5/10 then you can add 4/10 and 5/10 to get 9/10 which cannot be simplified so Kevin and Tiana have 9/10 of a pound on onions
