If you would like to solve the equation 1 2/5 * x = 7, you can calculate this using the following steps:
1 2/5 * x = 7
7/5 * x = 7 /*5/7
x = 7 * 5/7
x = 5
The correct result would be 5.

Answer:
6.8% decrease
Step-by-step explanation:
a drop of 8% means that only 92% of 125 boys remained on honor roll from last year; .92 x 125 = 115
a drop of 5% means that only 95% of 80 girls remained on honor roll from last year; .95 x 80 = 76
total number of students on honor roll last year = 125 + 80 = 205
total number of students on honor roll this year = 115 + 76 = 191
percent of change = (191 - 205) ÷ 205 = -14/205 = -.068
-.068, which represents a 6.8% decrease
