Which improper fraction is represented by the model?<br> 12 / 4<br> 10 / 3<br> 12 / 3

Ksivusya [100]

Answer:

$\frac{10}{3}$

Step-by-step explanation:

each circle is composed of 3 sectors

The first 3 are completely shaded representing 3 + 3 + 3 = 9 sectors

the last one has 1 sector of 3 shaded representing 1 sector

sectors shaded = 9 + 1 = 10

improper fraction is then $\frac{10}{3}$

A pineapple is 7 times as heavy as an orange. the pineapple also weighs 870 grams more than the orange. what is the total weight

san4es73 [151]

Let's translate each sentence into "Math".

Pineapple = p

Orange = x

is means equal

Pineapple is 7 times as heavy as an orange: p = 7x

Pineapple weighs 870 grams more than orange. p = 870 + x

Substitute p = 7x into the second equation:

7x = 870 + x

Subtract x from both sides

6x = 870

divide by 6

x = 145

The orange weighs 145 grams.

The pineapple weights 7 times the orange = 7(145) = 1015 grams.
