The value of x is 0.1810
Step-by-step explanation:
Given the equation as;
1.2÷0.375 - 0.2/6 * 4/25 ÷ 15 2/5 +0.8 = 0.016 ÷ 0.12 +0.7/x
This can be written as;
1.2÷0.375-0.4/75÷77/5+0.8=0.016÷0.12+0.7/x
Apply BODMAS style (Brackets, Of, Division,Multiplication,Addition and Subtraction) where in this case you start with division
(1.2÷0.375)-(0.4÷75) ÷ 77/5 +0.8 = (0.016÷0.12) +0.7/x
3.2 - 0.00533 ÷ 15.4 +0.8 =0.133+0.7/x
3.2-0.0003461+0.8=0.133+0.7/x---------------apply addition
3.2+0.8 -0.0003461-0.133=0.7/x
4-0.0003461-0.133=0.7/x
3.867=0.7/x
0.7/3.867=x
0.1810=x
