Answer:
120 ways
Step-by-step explanation:
To solve the question above, we use combination formula:
Where ;
nCr = n! / (n-r)! r!
10C7 = 10! / (10 - 7)! 7!
10C7 = 10! / 3! 7!
10C7 = (10 * 9 * 8) / 3 * 2 * 1
10C7 = 720 / 6
= 120 ways

Answer:
1/5 of a cup
Step-by-step explanation:
Answer=1/24
1/3+5/8=
to solve for this, we need the denominators of the fractions to match.
The LCM of 3 and 8 is 24
1/3=8/24
5/8=15/24
8/24+15/24=23/24
Now if we're using 23/24, then only 1/24 is left.
24/24-23/24=1/24
