Jessica has to mow the lawn. She mowed 1/3 then took a break. She then mowed 1/4 and took another break. Then she mowed 2/10 of the lawn. She went to a friend's house and did not finish the lawn. How much was left to mow?

1/3 + 1/4 + 2/10 or (1/5) = ****

LCD = 3 x 4 x 5 =60 , therefore...

20/60 + 15/60 + 12/60 = 47/60 completed; and 13/60 yet to be mowed

Thank you. What is the fraction to be mowed? I was thinking 1/4, 2/3, something like that.

To be mowed is 13/60 ths or a lottle more than 1/5

Thank you.

1/3 + 1/4 + 2/10 =
change it to the same common denominator , a number that 3, 4, and 10 will divide into evenly, like 60. So,

20/60 + 15/60 + 12/60 = 47/60, so
that leaves 13/60; which cannot be broken down into simpler terms.

This problem is actually adding fractions with different denominators.
