Question

(7 4/9 −8)∙3.6–1.6∙( 1/8 − 3/4 )+1 2/5 ÷(−0.35)

Answer 1

Answer:

-4.10

Step-by-step explanation:

We have so solve $(7\tfrac{4}{9}-8)(3.6)-(1.6)(\frac{1}{8}-\frac{3}{4})+1\tfrac{2}{5}\div (-0.35)$

To solve this expression we will use BODMAS.

B ⇒ Bracket

O ⇒ open

D ⇒ Divide

M ⇒ Multiplication

A ⇒ Addition

S ⇒ Subtraction

First we will solve inside the brackets.

(1) $(7\tfrac{4}{9}-8)=\frac{69}{9}-8=(\frac{67-72}{9})=(\frac{-5}{9})$

(2) $(\frac{1}{8}-\frac{3}{4})=\frac{1-6}{8}=(\frac{-5}{8})$

Now expression becomes

$(\frac{-5}{9})(3.6)-(1.6)(\frac{-5}{8})+\frac{7}{5}\div (-0.35)$

= $(-5)(0.04)-(0.02)(-5)+\frac{7}{5}\times \frac{1}{(-0.35)}$

= $(-0.20)-(-0.10)+\frac{1}{5(-0.05)}$

= $-.20+.10-\frac{1}{.25}=-.20+.10-4$

= -4.20 + 0.10 = -4.10
