Answer:
$22.20
Step-by-step explanation:
We are told that $13.32 only covered 3/5 of the cost. Does this mean it covered the whole cost? No. The 5 in the denominator represents the whole cost, and the 3 represents the fraction of the cost. In this case, 13.32 represents the 3, as it did not cover the whole cost.
Let's set up our equation by making 13.32 into a fraction.
13.32/x
We will represent the present's actual cost with the letter x.
13.32/x = 3/5
We want to make sure the 13.32 is in the numerator, equal to the 3 in the numerator in the 3/5 number, because we know that $13.32 only covered for a <em>fraction </em>of the present's cost, not the whole cost.
We solve this by doing cross multiplication. Multiply the 13.32 by the 5.
13.32 x 5 = 66.6
Next we divide 66.6 by 3 to get 22.2
66.6/3 = 22.2
This gives us our final answer of $22.20. This means that the cost of the original present was $22.20
You can find the answer by multiplying the length by the width by the height, then rounding your quotient to the nearest whole number. Or you can round the length, width, and height (5 x 5 x 3) and your answer would be your quotient. The answer would be either 70 or 75. There are a variety of ways to answer this question.
well first put it as a fraction so 29/9 and then divide which would give u the answer of 3.2 i hoped i helped
First, we have to find the ratio of quarters to the ratio of total coins:
15/15+8+27 = 15/50
Then, multiply the ratios:
15/50 * 14/49
(14/49 since one quarter has already been removed)
210/2450
21/245 = 0.0857
The probability is about 9 percent.
