Question 996122: If Ruth can run 2/3 of a mile in 1/4 of an hour how far can she run in 1 hour
Answer by addingup(3677)   (Show Source):
You can put this solution on YOUR website! how many quarters in 1 hour?
1/4+1/4+1/4+1/4= 4/4 There are 4 quarters in one hour
She can run 2/3 mile in 1/4 and we have 4 quarters:
2/3 x 4 Turn the 4 into a fraction - any number can be turned into a fraction by putting it over 1, like this:
2/3 x 4/1 Multiply - multiplication of fractions is straight across:
2 x 4/3 x 1= 8/3 We can turn this fraction into a mixed number:
8 goes into 3 twice (2 times) and we have a remainder or 8-(3x2)= 2:
She can run in one hour 2 and 2/3 miles
