<span>Carol noticed that 7/10 of the children playing soccer were girls. Which statement could be correct? A. There were 28 girls and 12 boys playing soccer. 28 : x% = 40 (the total number of children) : 100% 40x = 28 * 100 40x = 2800 x = 2800 / 40 x = 70% There were 70% of girls in the class. 70 / 100 = 0.7 7/ 10 = 0.7 This is why A is the correct answer.
To solve 4-12 on a number line you would need to start on 4 then move 12 places to the left since 12 is negative. Twelve would be negative because you cant take away 12 from 4 . When you move 12 places to the left you would get -8
