Answer:
.75 < 7/8
Step-by-step explanation:
Lets change the decimal to a fraction
.75 = 75/100
Divide the top and bottom by 25
75/100 = 3/4
Multiply by 2/2
3/4*2/2 = 6/8
6/8 < 7/8
so .75 < 7/8
Answer:
One less than 25, 24, times five is 120, and that is 4 times as much as 30 so you already know it is wrong.
Step-by-step explanation:
Solve the problem yourself first, to see if Pedro made any mistakes.
4/7 x 8/5
4x8 = 32
7x5 = 35
32/35 is the answer.
Pedro made his error in step 2, he cross multiplied instead of multiplying the numerators, and then the denominators.
To find out, all you have to do is divide 91980 by 36. Doing this will give you the result 2,555. This means that 36 can go into 91980 2,555 times.
I am assuming this is a triangle.....P = a + b + c
P = 2a - 3 + 2a + 3a + 1....combine like terms
P = 7a - 2 <==
