Answer:
1 5/32
Step-by-step explanation:
First, find common denominators. What you do to the denominator, you must do to the numerator.
First, multiply 4 to both the numerator and denominator of the second fraction:
(7/8)(4/4) = (7 * 4)/(8 * 4) = 28/32
Next, add across:
9/32 + 28/32 = 37/32
Simplify. Turn the improper fraction into a mixed fraction:
37/32 = (32 + 5)/32 = 1 5/32
1 5/32 is your answer.

The required number of red cards is 9 in the pile.
Given that,
The number of black cards in a pile is 4 times the number of red cards. There are 36 black cards in the pile.
To determine how many red cards are there.
<h3>What is arithmetic?</h3>
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Let the number of the red cards be r, and the number of the black cards be b
Black cards in a pile are 4 times the number of red cards.
b = 4r
Now,
There are 36 black cards in the pile.
b = 36
4r = 36
r = 36 / 4
r = 9
Thus, the required number of red cards is 9 in the pile.
