[ 1/1 Equation]
Work: Find the solution of equation x*0.89*1.65*1.65*2.99 = 3.7 .
Question type: Equation
Solution:Original question:
| x | × | 89 100 | × | 33 20 | × | 33 20 | × | 299 100 | = | 37 10 |
| Left side of the equation = | x | × | 28979379 4000000 |
28979379 4000000 | x | = | 37 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 37 10 | ÷ | 28979379 4000000 |
| = | 37 10 | × | 4000000 28979379 |
| = | 37 | × | 400000 28979379 |
We obtained :
| x | = | 14800000 28979379 |
Convert the result to decimal form :
| x | = | 0.510708 |
