Tell whether the ratios form a proportion. 25/16 , 65/56
1 answer:
Answer:
The two ratios given: 25/15 and 65/56 do not form a proportion.
Step-by-step explanation:
A proportion is formed when two ratios (or fractions) are equal. When you set the two ratios equal to each other:
You can then determine if they are equal by a few different methods. (1) You can cross-multiply the numbers and see if they are equal:
25 x 56 = 16 x 65 or 1040 ≠ 1400
You can also see if the numerators and denominators can be divided to form a common factor:
65 ÷ 25 = 2.6 and 56 ÷ 16 = 3.5
Since neither the products of cross-multiplication or the factors by division are equal, these two ratios do not form a proportion.

Given :
Miki has 104 nickels and 88 dimes.
She wants to divide her coins into groups where each group has the same number of nickels and the same number of dimes.
To Find :
Largest number of groups she can have .
Solution :
In the given question we need to find the largest number of groups she can have i.e we have to find the LCM of 104 and 88 .
Now , factorizing both of them , we get :
Form above , we can say that common factors are :
Therefore , the largest number of groups she can have is 8 .
Hence , this is the required solution .
