Esteban has a big jar of change in his room. There are 600 coins in total and 240 of them are pennies. What percent of the coins are pennies?

The fraction represents the number of pennies out of all the coins in the jar. To find what percent of pennies are in the jar, we can turn the fraction into a percent.

We can first simplify the fraction by dividing both the numerator and denominator by the Greatest Common Factor of 240 and 600 using 120.

240 ÷ 100 = 2

600 ÷ 120 = 5

2 ÷ 5 = 0.4

0.4 × 100 = 40%

Therefore, 40% of the coins were pennies.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
