Answer: 5 : 3 1/8 = 8 : 5
Step-by-step explanation:
Change values to whole numbers.
Convert any mixed numbers to fractions.
Convert 3 1/8
3 1/8 = 25/8
We now have:
5 : 3 1/8 = 5 : 25/8
Convert the whole number 5 to a fraction with 1 in the denominator.
We then have:
5 : 3 1/8 = 5/1 : 25/8
Convert fractions to integers by eliminating the denominators.
Our two fractions have unlike denominators so we find the Least Common Denominator and rewrite our fractions as necessary with the common denominator
LCD(5/1, 25/8) = 8
We now have:
5 : 3 1/8 = 40/8 : 25/8
Our two fractions now have like denominators so we can multiply both by 8 to eliminate the denominators.
We then have:
5 : 3 1/8 = 40 : 25
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 40 and 25 is 5
Divide both terms by the GCF, 5:
40 ÷ 5 = 8
25 ÷ 5 = 5
The ratio 40 : 25 can be reduced to lowest terms by dividing both terms by the GCF = 5 :
40 : 25 = 8 : 5
Answer:
The two consecutive even numbers are 12 and 14.
Step-by-step explanation:
Set up the equation, which turns out to be a quadratic, solve for n:
We are looking for positive even numbers, so the solution -7 is not valid. The solution for n is 6, and the two consecutive even numbers are:
2*6=12
2*7=14
Test: 12*12 + 14*14 = 340
2+6=8
8 units
6/8=3/4=0.75 per unit
2 times 0.75=1.5
6 times 0.75=4.5
