SOLVE THE EQUATION.
4 2/5x = 12 1/10
a. 7 7/10
b. 2 3/4
c. 2 1/2
d. 4/11
thank you Damon
(4 2/5) x = 12 1/10
or
(22/5) x = 121/10 multiply both sides by 10
44 x = 121
x = 121/44 = 2 3/4
so, B. 2 3/4. ur welcome. :>
4 2/5x = 12 1/10
(22/5) x = 121 / 10
(44/10) x = 121 / 10
44 x = 121
x = 121 / 44
well 44 * 3 = 132 too big
44 * 2 = 88
and 121 - 88 = 33
so
2 33/44
= 2 3/4
=============================
checl
2.75 * 4.4 = 12.1
sure enough, 12.1 is on the right
