A number is 75% of 85
sleet_krkn [62]

If a number is 75% of 85, the value of the number is 63.75.

<h3>What is 75% of 85?</h3>

Let the number the represented by 'x'

Such that; 75% of 85 = x

Solve for x.

75% of 85 = x

75% × 85 = x

75/100 × 85 = x

x = ( 75 × 85 )/100

x = 6375/100

x = 63.75

Therefore, if a number is 75% of 85, the value of the number is 63.75.

Solve: -(19/2) ÷ 38/7
Luden [163]

Answer:

(-1)/28

Step-by-step explanation:

Simplify the following:

((-19)/2×1/38)/7

(-19)/2×1/38 = (-19)/(2×38):

((-19)/(2×38))/7

(-19)/(2×38)×1/7 = (-19)/(2×38×7):

(-19)/(2×38×7)

The gcd of -19 and 38 is 19, so (-19)/(2×38×7) = (19 (-1))/(2 (19×2) 7) = 19/19×(-1)/(2×2×7) = (-1)/(2×2×7):

(-1)/(2×2×7)

2×2 = 4:

(-1)/(4×7)

4×7 = 28:

Answer: (-1)/28
