Step-by-step explanation:
What is your first expression? because i can not answer without the first expression.
It should be bigger, think of a pie:
if you cut it into 2 parts, the pieces are big
if you cut it into 4 parts, the pieces are smaller
in both parts, the AMOUNT OF PIE stays the same, the size changes
here, we cut out 8 / 10 pieces, (manny)
ana has the same WHOLE amount, but in BIGGER pieces because she has an amount less than 8.
It works if you REDUCE THE FRACTION, 8/10 can be REDUCED to 4/5, Ana's pieces should be twice as big as Manny's, but she only has 4
It cannot be 30, because the sum of two sides should be more than third side
-not D
10+18=28 <30
it cannot be 6 +10 < 18
it cannot 8
8+10=18
so it is has to be C) 12
12+18>10
10+12>18
10+18>12
answer C. 12 cm
