Start by finding the weight of the mother of the rhino calf in pounds.
about 300 pounds
Practice makes perfect
We are given that a rhino calf weighs about 3.8 % as much as its mother. We want to find about how many pounds the rhino calf weighs if its mother weighs 3.75 tons. We will start by finding the weight of the mother in pounds. Let x represent the weight of the mother in pounds. Recall that 1 ton is equal 2000 pounds. We can use this information to write the following proportion.
1ton/2000pounds=3.75ton/xpounds
Let's solve the proportion for x using cross products. We can ignore the units for now to keep our calculations simple.
We got that x=7500 is the solution to the proportion. This means that the mother of the rhino calf weighs 7500 pounds. Now we can find the weight of the calf in pounds, which we know is 3.8 % of 7500 pounds. Let's start by rounding the percent.
3.8 %of 7500 ≈ 4 %of 7500
To find 4 % of 7500, we need to multiply 4 % by 7500.
4 %of 7500 = 4 %* 7500
Before we perform the multiplication, we will write the rounded percent as a fraction and reduce it to its simplest form. We can write a percent as a fraction by writing the number part as a numerator over 100.
