Question 5.
Lexi needs 144 beads. A large box holds 100 beads. A medium box holds 10 beads. A small box holds 1 bead. Lexi already has 1 large box and 4 small boxes. How many medium boxes of beads does she need?
(A) 104
(B) 4
(C) 40

Explanation:
The total number of needs Lexi needs=144
The number of beads a large box can hold=100
The number of beads a medium box can hold=10
The number of beads a small box can hold=1
The number of large boxes she has already=1
The number of small boxes she has already=4
The number of medium boxes she has=X
We need to find out the number of medium boxes so that he could have 144 beads.
As we know 1 large box=100 beads
1 small box=1 bead, likewise 4 small boxes means Lexi is having 4 beads.
The total number of beads he has now=100+4=104.
Now to calculate the remaining beads we need to subtract the total beads he needs and the beads he has now.
Now we got the remaining beads from this we can calculate the medium boxes.
X=40/10
X=4.
Therefore, she needs 4 medium bags.

Question 6.
Carla’s bead order includes 3 boxes of 100 beads. Which could be the number of beads in Carla’s order?
(A) 263
(B) 230
(C) 314

Explanation:
The number of boxes of beads he includes in order=3
The number of cookies in each box=100
Here asked the question this 300 beads also included and in tens and ones place might have some number of cookies. Here 300 cookies are given so I prefer option c. And moreover, 3 is in the hundreds place.

Question 7.
Tess has 2 boxes of 10 beads, 4 boxes of 100 beads, and 6 boxes of single beads. How many beads does Tess have in all?
(A) 642
(B) 426
(C) 246

Explanation:
The number of boxes of beads Tess have=2 (medium box)
The number of beads in each box=10
The total number of beads in 2 boxes=2*10=20
The number of boxes of beads Tess have=4
The number of beads in each box=100 (large boxes)
The total number of beads in 4 boxes=4*100=400
The number of boxes of beads Tess have=6 (small boxes)
The number of beads in each box=1
The total number of beads in 6 boxes=6*1=6
20+400+6
=426.
