Explanation:
"before subtracting the fractions we require them to have"before subtracting the fractions we require them to have
"a "color(blue)"common denominator"a common denominator
"this is achieved by multiplying numerator/denominator"this is achieved by multiplying numerator/denominator
"of "2/3" by 2, thus making the denominator 6"of 23 by 2, thus making the denominator 6
rArr5/6-((2xxcolor(red)(2))/(3xxcolor(red)(2)))⇒56−(2×23×2)
=5/6-4/6=56−46
"now subtract the numerators leaving the denominator"now subtract the numerators leaving the denominator
=(5-4)/6=1/6=5−46=16
Make both numbers have a common denominator of 6, then just subtract to get
Explanation:
To subtract the numerators (numbers at the top), find a common denominator (number at the bottom), which in this case I'll use 6, since 6 is a common multiple of both 6 and 3
