Question

0,4063 : (4/5 - 3/8) =

Answer 1

1)4/5=0,8
2) 3/8=0,375
3) 0,8-0,375=0,425
4) 0,4063/0,425=0,956

Answer 2

0.4063:17/40= 4063/1000*40/17=239/250

Answer 3

To solve the expression, we need to simplify the fraction within the parentheses first and then perform the division.

The first step is to find a common denominator for 5 and 8, which is 40. Then we can rewrite the fractions as follows:

4/5 = (4 * 8) / (5 * 8) = 32/40 3/8 = (3 * 5) / (8 * 5) = 15/40

Now, we can substitute these values back into the expression:

0.4063 / (32/40 - 15/40)

Next, we can subtract the fractions inside the parentheses:

32/40 - 15/40 = (32 - 15) / 40 = 17/40

Substituting this back into the expression:

0.4063 / (17/40)

To divide by a fraction, we can multiply by its reciprocal. So, we can rewrite the expression as:

0.4063 * (40/17)

Now, we can multiply the numbers:

0.4063 * (40/17) ≈ 0.9541

Therefore, 0.4063 divided by (4/5 - 3/8) is approximately equal to 0.9541.
