Question

( 7 3/5 - 2 4/15) * 9/32

Answer 1

7 3/5-2 4/15=7 9/15-2 4/15=5 5/15=5 1/3;
5 1/3×9/32=16/3×9/32=3/2=1 1/2=1,5.

Answer 2

To calculate the expression (7 3/5 - 2 4/15) * 9/32, we first need to convert the mixed numbers into improper fractions.

7 3/5 can be converted to an improper fraction as follows: 7 * 5 = 35 35 + 3 = 38 38/5

2 4/15 can be converted to an improper fraction as follows: 2 * 15 = 30 30 + 4 = 34 34/15

Now, let's substitute the improper fractions back into the expression and simplify:

(38/5 - 34/15) * 9/32

To subtract the fractions, we need to find a common denominator. The least common multiple (LCM) of 5 and 15 is 15. Let's adjust the fractions:

(38/5 - 34/15) * 9/32

(38/5 * 3/3) - (34/15) * 1/1) * 9/32

(114/15 - 34/15) * 9/32

(80/15) * 9/32

To multiply the fractions, we multiply the numerators and denominators:

(80 * 9) / (15 * 32)

720 / 480

Simplifying the fraction, we can divide both the numerator and the denominator by their greatest common divisor, which is 240:

720/480 = (720/240) / (480/240) = 3/2

Therefore, (7 3/5 - 2 4/15) * 9/32 is equal to 3/2.
