Radar, the world’s largest horse, weighs 2,540 pounds. Thumbelina, the world’s smallest horse, weighs 57 pounds. How much more does Radar weigh than Thumbelina? (Source: Guinness Book of World Records,2008)
Answer = (1) pounds
Correct Answer
Explanation
We will carefully read the problem, looking for a key word or phrase. Key words and phrases indicate which arithmetic operation(s) should be used to solve the problem.
In the second sentence of the problem, the phrase How much more indicates that we should subtract the weights of the horses. We translate the words of the problem to numbers and symbols.
The number of pounds more that Radar weighs is equal to the weight of Radar minus the weight of the Thumbelina.
The number of pounds more than Radar weighs = 2,540 - 57
Use vertical form to perform the subtraction:
\( \begin{array}{r} \phantom{-}\,2,\overset{4}{\not{5}}\overset{\overset{13}{\not{3}}}{\not{4}}\overset{10}{\not{0}}\\ -\phantom{-}\underline{\phantom{1111}57}\\[4pt] \phantom{-}\,2,483 \end{array} \)
Radar weighs 3,483 pounds more than Thumbelina.
