42 of the 150 employees at Carlo's Car Repair wear contact lenses. What percent of the employees wear contact lenses?
antiseptic1488 [7]
\frac{42}{150} ÷ 2 = \frac{21}{75}

\frac{21}{75} ÷ 3 = \frac{7}{25}

\frac{42}{150}= \frac{7}{25}

Then, divide 7 by 25 because 25 is the divisor

7 ÷ 25 = 0.28

28% is the answer (:

A water tank was 1/8 full of water
vekshin1

Answer:

16,800 Liters

Step-by-step explanation:

Convert 3/4 into eighths, because it was already 1/8 full before the 10,500 liters were added:

3/4= 6/8

Subtract 1/8 from that (because it was already 1/8 full):

6/8-1/8= 5/8

Divide 10,500 by the 5 (because you want how many liters each part is):

10,500/5= 2,100

You know can say that every eighth is 2,100 Liters of water.

Multiply that by the 8 total parts it can hold:

2,100x8= 16,800 Liters
