You can't make it proper.You can only simplify.
Step 1: Factor both the numerator and denominator down to prime factors:<span>62 = 2 * 31 </span>
40 = 23<span> * 5</span>Step 2: Calculate the greatest common factor, GCF (also called greatest common divisor, GCD), by taking all the common prime factors of the numerator and denominator, by the lowest powers:gcd(2 * 31; 23<span> * 5) = </span><span>2 </span>
Step 3: Divide both the numerator and denominator by their greatest common factor, GCF (also called the greatest common divisor, GCD):62/40 =
(2 * 31)/<span>(23 * 5)</span> =
<span>((2 * 31) : 2)</span> / <span>((23 * 5) : 2)</span> =
31/<span>(22 * 5)</span> =
31/20Step 4: Improper fraction, rewrite:<span>31 : 20 = 1 and remainder = 11 => </span>
31/20<span> = </span>(1 * 20 + 11)<span> / </span>20<span> = 1 + </span>11/20<span> = 1 </span>11/20<span> as a </span>mixed number (also called mixed fraction).<span>1 + 11 : 20 = 1.55 as a </span>decimal number<span>.</span>
Answer: B. GCF of 72 and 81 is 9.
C. 72+81 = 9(8+9)
Step-by-step explanation:
The greatest common factor of two or more numbers is the highest number that divides all of them.
Given numbers : 72 and 81
Prime factorization of 72 and 81:
72 = 2 x 2 x 2 x 3 x 3
81= 3 x 3 x 3 x 3
GCF(72,81) = 3x 3 =9
Consider 72+81 = 9 x 8 + 9 x 9 [72= 8 x 9, 81 = 9 x 9]
= 9(8+9)
Hence, B. GCF of 72 and 81 is 9.
C. 72+81 = 9(8+9)

Answer:
Each can of soda costs about 33 cents.
Step-by-step explanation:
This is just a simple division problem, and you can find the answer by dividing the cost of the sodas by the total number of sodas, so 4/12. If you complete that problem, the answer is 0.33 repeating, and since it asks you to round to the nearest hundredth, the answer is just 0.33. It is in dollar amounts, so the answer is 33 cents.
