11.) our question issss.....
7 x __ = 420
all we have to do here is the opposite. so lets divide 420 by 7 here the math
420/7 = 60
sooooo answer is 60
12.) our question issss....
50 x __ = 0
well always keep in mind anything we multiply by 0 is going to be zero
so for example if we did 4 x 0 is would equal 0 because there arent even any rows to begin with
so your answer issss 0!
have a good one :)
merry christmas:D
Im guessing your saying how do you write 1.92 x 10 when you multiply you dont need to line up your decimals but it would lookm something like this:
1.92
x 10
and if it was 1.92 and 10.0 it would look like this
1.92
x 10.0
the deimals dont line up because you are multipling but if you were adding or subtrcating then you would have to line it up but not in this case
The answer is 2/3 because absolute value is always positive and a rational number is a fraction
Compound Interest
A = P(1 + r)^(n)
A = Amount, r = rate per year = 3.9% = 3.9/100 = 0.039, n = year = 3
A = P(1 + r)^(n)
A = 11000(1 + 0.039)^(3)
A = 11000(1.039)^(3) use calculator
A ≈ 12337.85
Compound Interest = A - P = 12337.85 - 11000 = 1337.85
So at the end of 3 years the Amount is ≈ £12 337.85 and the compound interest is ≈ £1 337.85
Hope this helps.
