Answer:

assuming all the / mean fractions (sorry i'm not sure)

first question:

4 and 2/5 is 22/5 (which is 44/10) and 1 and 7/10 is 17/10 so 44/10 - 17/10 = 27/10 (mixed number: 2 7/10)

second question:

5 and 2/3 is 17/3 (34/6) and 2 and 1/2 is 5/2 (15/6) so 34/6 - 15/6 = 19/6 (mixed number: 3 1/6)

third question:

17 (51/3) and 2 1/3 is 7/3 so 51/3 - 7/3 = 44/3 (mixed number: 14 2/3)

i think these are the answers, hope these help :D

Answer:

-48

Step-by-step explanation:

36/-3 = -12

-12 + 2(27/3 * -2)

27/3 = 9

-12 + 2(9 * -2)

9 * -2 = -18

-12 + 2(-18)

2 * -18 = -36

-12 + -36 = -12 - 36

Which is Bigger?

igomit [66]

A)
$43\%=\frac{43}{100} \\ \\
\frac{24}{60}=\frac{4}{10}=\frac{40}{100} \\ \\
43>40 \Rightarrow \frac{43}{100} > \frac{40}{100} \Rightarrow 43\% > \frac{24}{60}$

43% is bigger.

b)
$\frac{18}{30}=\frac{6}{10}=\frac{60}{100} \\ \\
0.51=\frac{51}{100} \\ \\
60>51 \Rightarrow \frac{60}{100} > \frac{51}{100} \Rightarrow \frac{18}{30} >0.51$

18/30 is bigger.
