whats the answer Lara spends 1 3/4 hours working out. She spends 2/5 of the time doing stretching exercises. How much time does she spend doing stretching exercises? Write the answer in simplest form.
To find out how much time Lara spends doing stretching exercises, we need to calculate 2/5 of 1 3/4 hours.
First, let's convert 1 3/4 hours to an improper fraction:
1 3/4 = (4/4 + 3/4) = 7/4
Now, let's calculate 2/5 of 7/4 hours:
(2/5) * (7/4) = (2 * 7) / (5 * 4) = 14/20 = 7/10
Therefore, Lara spends 7/10 of an hour doing stretching exercises.
what is the answer to this. Lars has 10 baskets of vegetables. Each basket contains 1 1/2lb of vegetables. What is the total weight of all the vegetables in the baskets? Convert the answer to a mixed number.
To find the total weight of all the vegetables in the 10 baskets, we need to multiply the weight of one basket by the number of baskets.
The weight of one basket is 1 1/2 lb, which can be written as 3/2 lb.
Now, let's calculate the total weight of all the vegetables:
(3/2 lb) * 10 baskets = (3/2 lb) * (10/1) = 30/2 lb = 15 lb
Therefore, the total weight of all the vegetables in the baskets is 15 lb, which can be written as the mixed number 15 0/1 lb.
