If the three-fifth of a number is equal to 70% of another number, what...
Let the numbers be a and b.
So, according to the question,
a * 3/5 = 70% of b
3a/5 = 70b/100
a/b = (70 * 5)/(100 * 3) = 7/6
So, the ration between a and b is 7 : 6.

If the three-fifth of a number is equal to 70% of another number, what...
Let's assume the first number is x and the second number is y.
According to the given information, three-fifths of x is equal to 70% of y. Mathematically, we can represent this as:
(3/5)x = (70/100)y
Simplifying the above equation, we get:
(3/5)x = (7/10)y
To find the ratio between x and y, we need to divide both sides of the equation by y:
(3/5)x / y = (7/10)y / y
Simplifying further, we get:
(3/5)x / y = 7/10
Now, we can cross multiply to find the ratio:
10 * (3/5)x = 7 * y
Simplifying this equation, we get:
(30/5)x = 7y
6x = 7y
Finally, we can write the ratio between x and y as:
x : y = 7 : 6
Therefore, the correct answer is option 'B' - 7 : 6.
According to the given information, three-fifths of x is equal to 70% of y. Mathematically, we can represent this as:

Simplifying the above equation, we get:
(3/5)x = (7/10)y
To find the ratio between x and y, we need to divide both sides of the equation by y:
(3/5)x / y = (7/10)y / y
Simplifying further, we get:
(3/5)x / y = 7/10
Now, we can cross multiply to find the ratio:
10 * (3/5)x = 7 * y
Simplifying this equation, we get:
(30/5)x = 7y
6x = 7y
Finally, we can write the ratio between x and y as:
x : y = 7 : 6
Therefore, the correct answer is option 'B' - 7 : 6.
