Charles reads quickly he reads 1 3/7 pages every 2/3 of a minute. how many pages does he read per minute?

Answers

Answer 1

Answer: First, I'd suggest finding a common denominator for your two fractions. Since 7 and 3 both go into 21, let's use that.

2/3 becomes 14/21, because 3 x 7 = 21, and 2 x 7 = 14
1 3/7 becomes 1 9/21, because 7 x 3 = 21, and 3 x 3 = 9

Now, to make the rest of it a bit easier, let's turn the fractions into decimals.

14/21 is 0.66
1 9/21 is 1.43

We can then turn this into a ratio, and then write an equation to solve for how many pages Charles reads per minute.

1.43 pages per 0.66 minutes, or 1.43/0.66

The equation to solve for this would then be
$(1.43)/(0.66) = (p)/(1)$
where p is the number of pages.

To solve for p, we simply cross multiply and divide.
1.43 x 1 = 0.66 x p
1.43 = 0.66 x p
1.43 ÷ 0.66 = p
p = 2.17

Charles reads 2.17 pages per minute.

A coffee shop uses 4 liters of milk every day.a. If there are 15 liters of milk in the refrigerator, after how many days will more milk need to be purchased? Explain how you know.
b. If only half as much milk is used each day, after how many days will more milk need to be purchased?

Answers

Answer:

explained

Step-by-step explanation:

a. daily requirement of milk = 4 liters

15 liters of milk is present

this 15 liters of milk will be used up in $(15)/(4)$ days

= 3(3/4) days , so after 3 days only more milk will be required to purchase.

b. daily milk consumption is reduced to half = 2 liters

Now, 15 liters of milk will be used up in $(15)/(2)$ = 7.5 or 7(1/2) days.

Hence now milk will be purchased after 7 days.
