Romashka [77]

Answer:

The truck is hauling 3/4 of a full load

Step-by-step explanation:

we know that

2/3 ton of gravel represent the 100% of a full load

Find out how much of a full load the truck is hauling with 1/2 ton of gravel, using proportion

Let

x ----> the percentage of a full load

$\frac{(2/3)}{100\%}=\frac{(1/2)}{x}\\\\x=100\%(1/2)/(2/3)\\\\x=100\%(3/4)\\\\x=75\%$

Convert to fraction number

$75\%=\frac{75}{100}=\frac{3}{4}$

therefore

The truck is hauling 3/4 of a full load

Andrew is trying to create a number puzzle for his younger sister to solve. He challenges his sister to find the mustery number.

yan [13]

She is not correct b/c if you solve the problem the mystery number is 18.

1/2m-4=5
+4 +4
1/2m=9 divide 9 by 1/3

m=18

You can check by replacing the m with 18 in the original equation and it will equal to 5.
