Question 6.
CHALLENGE Jose has a bag of marbles. There are 8 red marbles in the bag. There are twice as many green marbles as red marbles. There are 2 fewer blue marbles than green marbles. There are half as many white marbles as blue marbles.

a. How many marbles are in the bag? Show your work.
Bridges in Mathematics Grade 2 Home Connections Unit 5 Module 4 Answer Key 11
There are _____________ marbles in the bag.
Answer:
There are 8 red marbles in the bag.
There are twice as many green marbles as red marbles.
Twice of red marbles means add red marbles two times.
8 + 8 = 16 marbles
There are 16 green marbles.
There are 2 fewer blue marbles than green marbles.
Subtract 2 marbles from 16 green marbles the difference is equal to 14.
16 – 2 = 14
There are 14 blue marbles.
There are half as many white marbles as blue marbles.
Divide 14 blue marbles by 2 the result is equal to 7.
14/2 = 7
There are 7 white marbles.
8 + 16 + 14 + 7 = 45
There are 45 marbles in the bag.
