Lacy runs 5 1/4 km on Thursday. She runs 1 1/2 times as far on Saturday. How many km did she run on Saturday? Express your answer as a fraction.

The answer to your question is: 7 7/8 km

Step-by-step explanation:

Data

Lacy runs 5 1/4 km

runs 1 1/2 times as far on Saturday

Km run on Saturday = ?

First calculate 1/2 of 5 1/4 convert 5 1/4 into an improped fraction

5 1/4 = 21/4

Now, divide by two (21/4) / 2 = 21 / 8

She ran 5 1/4 + 21/8 Solve the sum

= 21/4 + 21/8 = (42 + 21) / 8 = 63 / 8 = 7 7/8 km
