Answer:
There are 13 diamond cards in a deck of cards 13 x 4 = 52 so the answer is 1/4 :)
Step-by-step explanation:
Answer: 15 + 53/77
Step-by-step explanation:
Multiplying a fraction by 1 does not change the value.
Any number divided by itself is 1.
For instance, 11/11 = 7/7 = 1.
12 + 1/7 + 3 + 6/11 = 15 + 1/7 + 6/11
= 15 + (11×1)/(11×7) + (7×6)/(7×11)
= 15 + 11/77 + (6×7)/77
= 15 + (11 + 6×7)/77
= 15 + 53/77
It is faster to make sure to multiply by the "smallest" form of one that will work, but you don't have to. You only need to make sure that at the end there are no common factors in numerator and denominator, and that numerator is smaller than denominator.

And
Answer:
A. 4 B. log₂(2^4)
Step-by-step explanation:
A. log₂ 2 = log₂ 2¹ = 1
log₂ 8 = log₂ 2³ = 3
log₂ 2 + log₂ 8 = 1 + 3 = 4
B. *log₂ 2⁴ = 4
