How do you simplify #1/3(21m + 27)#?

Answer 1

Both #21m# and #27# are divisible by #3#.. so we can do this easily #1/3(21m+27)=1/cancel3xxcancel21^7m+1/cancel3xxcancel27^9# We are left with #7m+9#

To simplify the expression ( \frac{1}{3}(21m + 27) ), distribute the fraction across the terms inside the parentheses:

[ \frac{1}{3}(21m + 27) = \frac{1}{3} \times 21m + \frac{1}{3} \times 27 ]

[ = 7m + 9 ]

Therefore, ( \frac{1}{3}(21m + 27) ) simplifies to ( 7m + 9 ).
