Answer: 3/10
Step-by-step explanation:
Given a decimal number 0.3
To Write the rational number 0.3 in the form ab , where a and b are integers, take it to be :
0.3 /1
Multiply the numerator and the denominator by 10
0.3/1 × 10/10 = 3/10
Therefore, a = 3 and b = 10
the rational number 0.3 in the form ab , where a and b are integers is
3/10

Answer:
26 candy bars and 12 sodas
Step-by-step explanation:
This problem can be solved by a simple system of equations
I am going to call x the number of candy bars that Sally bought and y the number of sodas that Sally bought.
The fact that she bought 38 itens means the x + y = 38.
She spent $50.38. The value she spent is the sum of the number of candy bars multplied by the value of the candy bar and the number of sodas multiplied by value of a soda. So 1.25x + 1.49y = 50.38
So we have to solve the following system:
1)x + y = 38
2)1.25x + 1.49y = 50.38
From 1), we have that x = 38 - y. I am going to replace it in 2)
1.25(38-y) + 1.49y = 50.38
-1.25y + 1.49y = 50.38 - 47.5
0.24y = 2.88
y = 12.
Sally bought 12 sodas.
In 1: x = 38-y = 38-12 = 26
Sally bourght 26 candy bars
