A number is 2/5 time another numbet.If their sum is 70, find the number
Answers
Answer:
Let one number be x. Therefore, according to the question, the other number will be 2/5 times x, which is 2/5×x or 2x/5
According to the question:
x+(2x/5)=70
=)(5x+2x)/5=70
=)5x+2x=70×5
=)7x= 350
=) x = 350/7
=)x= 50
Therefore 2x/5 = (2×50)/5 = 100/5 = 20
Therefore the numbers are 50 and 20

Answer:
the two required numbers are 50 and 20.
Step-by-step explanation:
First of all, we need to write this question in algebraic language.
We know that 2/5th of some number, say x, is equal to another numbe, say y. We also know that their sum is 70.
Now, we've 2 equations and 2 unkown quantities. The equations are,
2x/5 = y………(1)
and
x+y = 70……..(2)
By putting the value of y from (1), equation (2) will be modified as,
x+(2x/5) = 70.
Take LCM,
7x/5 = 70.
Solve for x and we get x as 50.
Since the sum of the 2 numbers is 70, the other number should be 20.
Ao, the two required numbers are 50 and 20.
Hope this helps
