the difference between two whole number is 66. the ratio of two number is 2:5 the two numbers are
Answers
Answer:
the numbers are 110 and 44
Step-by-step explanation:
let the number be x,
5x-2x=66
3x=66
x=66/3=22
the numbers are,
5*22=110
2*22=44
Answer:
GIVEN -
- Difference b/t two no. is 66
- Ratio of two no. is 2:5
To FIND -
- The no.
SOLUTION
Let the ratiob be 2x and 5x
according to the question -
5x - 2x = 66
3x = 66
x = 66/3
x= 22
5x = 5 × 22 = 110
2x = 2 × 22 = 44
VERIFICATION
5x - 2x= 66
110 - 44= 66
66= 66
LHS = RHS
hence , proved

• Whole no. - Numbers which is not in a fraction like 1, 2 ,3 , 4 etc.
• Prime no.- Numbers which has no factors except 1 and the no. itself is called prime no.
for ex.- 2 , 3 , 5 , 7
• Composite no.- Numbers which has atleast one factor except 1 and the no. itself is called composite no.
for ex - 4 , 6, 8
• Rational no.- All natural, whole, prime , composite no. are rational no.
A rational no. is one which can be written in the form of p/q where p and q are co- primes.
for ex- 2/1 , 2/3 , 5/8
• Irrational no.- Numbers which cannot be written in the form of p/q where p and q are co- primes are called irrational
for ex - root 2, root 3
• Real numbers - All rational and irrational together make up real numbers.
