Answer:

72

Step-by-step explanation:

mean x number of total test scores -> 75.2 x 5=376

sum of the four test scores given -> 304

difference of the two numbers -> 376- 304= 72

the missing test score, therefore the answer is 72.

My daughter is in 3rd grade. On a 3rd grade level how can she explain that 5/6 is greater than 5/8
blagie [28]
Well,5/6 is closer to one than 5/8 is,just add 1/6+5/6 and then you get 1,adding 1/8 to 5/8 is only 6/8,so that's how you can tell how it is greater! Hope this helps your daughter!
