Well first we need to find how we can turn 25 into 100
Well one way would be to multiply by 4
25 x 4 = 100
Since we multiplied the bottom number by 4 we should multiply the top number by 4.
So..
19 x 4 = 76
So our new fraction is..
76
-----
100
Now we can easily turn this into a decimal.
76/100 = 0.76
Answer = 0.76
Good Luck! :)

Kaylani is going to make a blanket by sewing a 4-foot long piece of ribbon along the diagonal of a piece of rectangular fabric. She wants the length of the blanket to be 18 inches longer than the width. What is the approximate perimeter of the blanket? Round to the nearest inch.
Based on the information given, it should be noted that the mean and standard deviation of Y will be 0.4899 and 0.699 respectively.
<h3>Calculating the mean.</h3>
Based on the information given, it should be noted that the probability distribution for y will be:
Y 0 1. 2
Probability 0.63. 0.25. 0.12
The mean of Y will be:
= (0 × 0.63) + (1 × 0.25) + (2 × 0.12)
= 0 + 0.25 + 0.25
= 0.49
The variance will be 0.4899. Therefore, the standard deviation will be:
= ✓0.4899
= 0.699
