How do you make 7.6 in to a mixed number

You turn 7.6 into 7 60/100 because 7 is the whole number and 6 or 60 are in the 10 or 100s place so you get can 7 60/100

First you have to find what .6 is in fraction form. The 6 is in the tenths place so that means it is 6/10
This gives you the mixed number of 7 6/10. But you still have to simplify the fraction. When divided by 2/2, 6/10 becomes 3/5.
7.6 = 7 6/10 = 7 3/5

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
