Question

e) 43.678 x 64.1
f) 1.678 / 0.42
g) 28.367 / 3.74
h) 4278 / 1.006

Explanation:

Step1: Calculate e) Multiply the two decimals

$43.678 \times 64.1 = 43.678\times(60+4+0.1) = 43.678\times60 + 43.678\times4 + 43.678\times0.1$
$=2620.68 + 174.712 + 4.3678 = 2799.7598$

Step2: Calculate f) Divide decimals, convert to integers

$\frac{1.678}{0.42} = \frac{167.8}{42} \approx 3.995$

Step3: Calculate g) Divide decimals, convert to integers

$\frac{28.367}{3.74} = \frac{2836.7}{374} \approx 7.585$

Step4: Calculate h) Divide by decimal, convert to integers

$\frac{4278}{1.006} = \frac{4278000}{1006} \approx 4252.485$

Answer:

e) $2799.7598$
f) $\approx 3.995$
g) $\approx 7.585$
h) $\approx 4252.485$
