Answer:
Ivan has 42 blue beads.
Step-by-step explanation:
We need to find how many blue beads Ivan has.
Blue beads = 6 times as many as red beans
b = 6r
r + b = 49
r + (6r) = 49
7r = 49
Divide both sides by seven to isolate r
r = 7
b = 6(7)
b = 42
To add 1/10 and 8/100, they must have the same denominator.
To do this, multiply 1/10 by 10/10 (which equals one, so it doesn't change the value of the fraction).
Now you have 10/100 and 8/100. To add them, simply add the numerators and keep the denominators the same.
This results in 18/100, which can be simplified to 9/50.
152,000
is the correct answer
