2. Cross multiplication method.
2/9-8/10 using LCM Method:
What is 2/9 minus 8/10 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/9
Fraction B: 8/10
What to be found?
2/9-8/10 = ?
Find what's the difference between 2/9 and 8/10.
step 2 Compare the denominators of fractions 2/9 and 8/10 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/9 and 8/10 are not equal, it is said to be unlike fractions subtraction.
step 3For unlike fractions subtraction, find the LCM (least common multiple) of both denominators of fractions 2/9 and 8/10:
The LCM of 9 and 10 is 90.
step 4 Write the fractions 2/9 and 8/10 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=2/9-8/10
=(2 x 90)/(9 x 90)-(8 x 90)/(10 x 90)
step 5 Simplify the expression to have common denominator:
=20/90-72/90
step 6 Take the common values out and rewrite the above expression like the below:
=1/90 x (20/1-72/1)
=1/90 x (20 - 72)
step 7Simplify the above expression further:
=1/90 x -52
= -52/90
=-26/45
2/9-8/10=-26/45
Hence,
2/9 minus 8/10 equals to -26/45 in fraction.
2/9-8/10 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/9
Fraction B: 8/10
What to be found?
2/9-8/10 = ?
Find what's the difference between 2/9 and 8/10.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (2 x 10), find the product of numerator of Fraction B and denominator of Fraction A (8 x 9), and find the product of both denominators of Fraction A and Fraction B (9 x 10) and rewrite the equation as like the below:
= (2 x 10) - (8 x 9)/(9 x 10)
step 3 Simplify and rewrite the fraction:
= (20 - 72)/90
= -52/90
= -26/45
2/9-8/10 = -26/45
Hence,
2/9 minus 8/10 = -26/45
