4/5 is in its simplest form.
Step-by-step explanation:
the lowest common denominator (LCD) is the lowest common multiple (LCM) of the denominator numbers (the ones at the bottom of the fractions).
finding the LCM of 9 and 12 using the prime factor method :
9 = 3×3
12 = 2×2×3
the LCM is the combination of the longest chains per prime factor. which means we have 2×2 and 3×3 as longest chains for 2 and 3.
LCD = LCM = 2×2×3×3 = 36
2/9 turns into x/36 by multiplying by 4/4 :
2/9 × 4/4 = 8/36
5/12 turns into x/36 by multiplying by 3/3 :
5/12 × 3/3 = 15/36
so, the third answer option is correct.
Your answer is 3
Why? Because 3^4 is 81
same as saying 3 x 3 x 3 x 3=81 :)
27/5 = 5 2/5 ft per blanket
5 2/5 falls in between 5 and 6
well you cant really be expecting us to answer all that, so make sure you specify exactly WHAT you want to be answered.
62. -2(x - 1) + 5x = 2(2x - 1)
...multiply -2
-2x + 2 + 5x = 2(2x - 1)
...multiply 2
-2x + 2 + 5x = 4x - 2
...simplify
3x + 2 = 4x - 2
...add 2
3x + 4 = 4x
...subtract 3x
4 = x
