Question

Simplify
$(3.2-1\frac{3}{5})+(2\frac{1}{4}\div 0.5)$

• A. 8.2
• B. 6.1
• C. 7.7
• D. 10.5

Answer 1

Answer:

B. 6.1

Let's simplify step by step.

Given:

$(3.2 - 1\tfrac{3}{5}) + \left(2\tfrac{1}{4} \div 0.5\right)$

1. Convert the mixed numbers:

• $(1\tfrac{3}{5} = 1.6)$

• $(2\tfrac{1}{4} = 2.25)$

So the expression becomes:

$(3.2 - 1.6) + (2.25 \div 0.5)$

2. Evaluate each bracket:

• (3.2 - 1.6 = 1.6)

• $(2.25 \div 0.5 = 4.5)$

3. Add the results:

1.6 + 4.5 = 6.1

Answer:

$\boxed{6.1}$
