.8
All percents are out of 100, so to figure out the answer you must make the denominator, or bottom number in your fraction, 100.
To get to 100, you would multiply 5x20, because that equals 100. Because you multiplied the denominator, which is 5, you must multiply the top number by 20 as well.
4x20 = 80
So therefore, the answer is 80/100, so .8
Answer:
$40.20
Step-by-step explanation:
$7.50 per hour. Tim worked for 2 hours so you would do 2 timez 7.5 which is $15, the total he earned from mowing.
$6.30 per hour. Tim worked for 4 hours so you would do 4 times 6.3 which is $25.2, the total he earned from washing windows.
To get the total of how much he earned all together you add 15 and 25.2 and you get $40.2.
Given that the ratio of three trays is A : B : C = 2 : 3 : 4
Let us consider the common factor among the number of trays be "x".
If we need to make a total of 171 trays, then the equation of sum of trays would be :-
Type A + Type B + Type C = 171
2x + 3x + 4x = 171
9x = 171
x =
= 19
So we have following number of trays :-
Number of type A trays = 2x = 38 trays.
Number of type B trays = 3x = 57 trays.
Number of type C trays = 4x = 76 trays.
Now if each tray contains 20 cookies, then we would have following arrangements :-
Cookies in type A trays = 38×20 = 760 cookies.
Cookies in type B trays = 57×20 = 1140 cookies.
Cookies in type C trays = 76×20 = 1520 cookies.
