Answer:
b. 97
Step-by-step explanation:
Home work = 88
20 % of 88 = 88 x 20/100 = 17.60
Quiz Average= 84
25 % of 88 = 84 x 25/100 = 21
Test Average= 92
40 % of 92= 92 x 40/100 = 36.8
Add all = 17.60 +21+ 36.8= 75.40
Let the marks be x in final exam
The percentage is 15 % and scores a 90 in a class we can write
15x/100 + 75.40 =90
0.15x= 90-75.40
0.15x= 14.60
x= 14.60/0.15= 97
final exam marks will be 97
Answer:
a)1 : 4 and 5 : 20
Step-by-step explanation:
If a ratio is a proportion that means the
quantity on the left hand side is lesser than the quantity on the right hand side; it's a part of a whole, a small fraction.
Example of proportion ratios:
4 : 7
7 : 29
90 : 200
68 : 140
Example of non-prpotion ratios:
7 : 4
80 : 19
29 : 20
When subtracting fractions, you only subtract the numerators. NEVER SUBTRACT THE DENOMINATORS. ONLY SUBTRACT THE NUMERA-
-TORS. So, subtract the numerators. 9 - 6 = 3 and the denominator is still the same. The answer is: 3/10
hope it helps!
