Answer 2

The lowest rational form required is $0.144\div 1.2\div 0.016\div0.02<strong>+</strong>7\div5-21\div 8=\frac{14951}{40}$

Step-by-step explanation:

Given : Expression $0.144\div 1.2\div 0.016\div0.02+7\div5-21\div 8$

To find : Simplify and express the result as a rational number in its lowest form?

Solution :

Expression $0.144\div 1.2\div 0.016\div0.02+7\div5-21\div 8$

$=0.12\div 0.016\div0.02+7\div5-21\div 8$

$=7.5\div0.02+7\div5-21\div 8$

$=375+1.4-2.625$

$=376.4-2.625$

$=373.775$

$=\frac{373775}{1000}$

$=\frac{14951}{40}$

Therefore, the lowest rational form required is $0.144\div 1.2\div 0.016\div0.02<strong>+</strong>7\div5-21\div 8=\frac{14951}{40}$
