Answer 2

1. 2.7 + 3/8 x 16.2 = 8,775

Pasos:

3/8 x 16.2 = 6.075

= 2.7 + 6.075

Sumar: 2.7 + 6.075 = 8.775

= 8.775

2. 3 ( 1/3 x 0.9 + 7/5 × 4 ) = 17.7

Pasos:

3 ( 0.9 x 1/3 x + 4 x 7/5 x )

Poner los parentesis utilizando:

$a(b + c) = ab + ac$

= 3 x 1/3 x 0.9 + 3 x 7/5 x 4

= 3 x 0.9 x 1/3 x + 3 x 4 x 7/5 x

Simplificar:

= 17.7

3. 5/6 x 2.7 - 1/4 = 2

4. 5/8 + 7/4 x 2.8 = 5.525
