Answer: 7/8= 35/40
3/10= 12/40
Step-by-step explanation: You can find the least common denominator by looking at a multiplication table or by multiplying the prime factors of the original denominators:
8 = 2×2×2. 10=2×5
"Cancel" the duplicate from one set or the other. So here one of the 2's is eliminated:
2×2×2×5=40
Then set up a proportion:
7/8 = x/40 Multiply the new denominator by the original numerator, then divide by the original denominator:
40×7=280. 280÷8=35
40×3=120. 120÷10=12

<h3>How to illustrate the information?</h3>
In mathematics, an algebraic expression is the expression that is built up from integer constants, variables, and the algebraic operations
It should be noted that an equation is a mathematical statement that is made up of two expressions connected by an equal sign.
For example, 3x – 5 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 7. This can be illustrated in the shape.

[C] 0.05b + 0.25s + 0.4n = 20
b = balloons
s = streamers
n = noisemaker
Since they already give us the price of each item we just need to add a variable at the end of each one since we don't know how many of each item is bought. Adding the costs of all the party supplies should not go over $20. We can automatically eliminate B and D. We can also eliminate A because the prices of each item are incorrect. Therefore, C is the correct answer.
Best of Luck!
