Answer 1

Answer:

2.1

Step-by-step explanation:

6/7 ( 3/8 ÷ 1.5 + 2 1/5 )

Solve for brackets first.

6/7 ( 0.375/1.5 + 2.2 )

Divide the two terms in the brackets.

6/7 (0.25+2.2)

Add the two terms in the brackets.

6/7 (2.45)

Multiply the two terms.

= 2.1

Answer 2

Answer:

$2\frac{1}{10}$

Step-by-step explanation:

Use BIDMAS

B = Brackets

I = Indices

D = Division

M = Multiplication

A = Addition

S = Subtraction

$\frac{6}{7} * (\frac{3}{8} /\frac{15}{10} +2\frac{1}{5} )$

→ Work out the division sum inside of the brackets

$\frac{3}{8} /\frac{15}{10} =\frac{3}{8} *\frac{10}{15} =\frac{30}{120} =\frac{1}{4}$

→ Write out new sum

$\frac{6}{7} *(\frac{1}{4} +2\frac{1}{5} )$

→ Work out the sum of the addition inside the bracket

$\frac{1}{4} +2\frac{1}{5} =\frac{1}{4} +\frac{11}{5} =\frac{5}{20} +\frac{44}{20 } =\frac{49}{20} =2\frac{9}{20}$

→ Write out new sum

$\frac{6}{7} *2\frac{9}{20}$

→ Solve

$\frac{6}{7} *2\frac{9}{20}=\frac{6}{7} *\frac{49}{20} =\frac{294}{140} =\frac{147}{70} = \frac{21}{10} =2\frac{1}{10}$
