The number of ways that he can make the fruit salad if it must contain watermelon is 35.
<h3>What is Permutation and combination?</h3>
Selection of the one object from the given samples with replacement or without replacement is called as the permutation. The selection of the items from the sample as they are different with each other.
The salad contains water melon, now we have to select 4 more fruits out of 7.
Using combination
= n! / r! (n-r)!
= 7!/ 4! (7-4)!
= 7*6*5*4! / 4! * 3*2
= 35
Hence, number of ways that he can make the fruit salad if it must contain watermelon is 35.

Answer:
c) The reduced form of the given fraction 
Step-by-step explanation:
Here, the given expression is "24 over 30".
The given expression is is equivalent to 
Now by Prime Factorization:
24 = 2 x 2 x 2 x 3
30 = 2 x 3 x 5
⇒ The common factors in 24 and 30 is 2 x 3 = 6
So, 
Hence the reduced form of the given fraction
Answer:
!. Scale factor = 5
2. Scale factor = 
Step-by-step explanation:
scale = 
1. To increase the numbers, let the scale factor be 
= 5. So that;
0.05 x 5 = 0.25
x 5 = 0.5 x 5 = 2.50
7 x 5 = 35.00
13 x 5 = 65.00
25 x 5 = 125.00
102 x 5 = 510.00
2. To decrease the numbers, let the scale factor be . So that;
0.05 x = 0.01
x = 0.5 x = 0.10
7 x = 1.40
13 x = 2.60
25 x = 5.00
102 x = 20.40
