Question

Calcule:

2/3 de 90
4/5 de 280
2/8 de 64
5/6 de 120
2/12 de 144
3/9 de 27
5/7 de 140​

Answer 1

Olá,

$\frac{2}{3} \times 90 = \frac{180}{3} = 60 \\ \\ \frac{4}{5} \times 280 = \frac{1120}{5} = 224 \\ \\ \frac{2}{8} \times 64 = \frac{128}{8} = 16 \\ \\ \frac{5}{6} \times 120 = \frac{600}{6} = 100 \\ \\ \frac{2}{12} \times 144 = \frac{288}{12} = 24 \\ \\ \frac{3}{9} \times 27 = \frac{81}{9} = 9 \\ \\ \frac{5}{7} \times 140 = \frac{700}{7} = 100$

Espero ter ajudado :-) Bons estudos.

Answer 2

Resposta:

Explicação passo-a-passo:

2/3 . 90 = 180/3 = 60

4/5 .280 = 224

2/8 . 64 = 16

5/6.120 = 100

2/12.144 = 288/12 = 24

3/9.27 = 9

5/7. 140 = 700/7 = 100
