Answer:
<em>Peter now has 54 baseball cards</em>
Step-by-step explanation:
<u>Percentages</u>
Assume Peter had x baseball cards in his collection. The 35% of his initial collection is
35 * x / 100= 0.35x
We know that those 14 new baseball cards represent a 35% of his previous collection, therefore we can set a simple equation
0.35x=14
When we solve for x, we'll know how many baseball cards Peter had before
x=14 / 0.35 = 40
Peter had 40 cards, he added 14 new baseball cards, so he now has 40+14=54
Peter now has 54 baseball cards
Answer
21/2:3 and 16:6 are not equivalent
Answer:
See the three examples, below:
Step-by-step explanation:
One way of approaching this would be to separate 48:
48 times 6 is equivalent to (40 + 8) times 6, or 240 + 48, or 288.
That's just one of many examples.
48 times 6 could also be expressed as 48 times (2 + 4) = 96 + 192 = 288.
And so on.
