:D

Answer 45

30 is 40% of what number?

Answer 46

40% of x=30
0.4x=30
0.4x/0.4=30/0.4
Right so far?

Answer 47

Sure

Answer 48

x=30/0.4

Answer 49

which is equal to what?

Answer 50

75

Answer 51

Yes, how did you figure that out?

Answer 52

What do you mean?

Answer 53

How did show that 30/0.4 = 75 ?

Answer 54

I divided 30 by 0.4

Answer 55

ok. Another way to do it is like this--this is how I was doing it in my head:
\[ \frac{30}{0.4} = \frac{30}{4/10} = \frac{30 \times 10}{4} = \frac{300}{4} = 75 \]

Answer 56

That looks more effective! Let me try!

Answer 57

64 64
--- = -----
0.125 1.25/10?

Answer 61

No wait

Answer 62

64 64
--- = -----
0.125 5/40?

Answer 63

Right sofar?

Answer 64

50% = 1/2
25% = 1/4
12.5% = 1/8

Answer 65

Ah

Answer 66

64 64*8
--- = ----- = 512?
1/8 1

Answer 67

Yes.

Answer 68
