3 * N = 1
The multiplicative inverse is just the reciprocal of the number. The reciprocal is just " flipping " the number. So the reciprocal of 3 (or 3/1) is 1/3. And any time u multiply a number by its multiplicative inverse (reciprocal), the result is 1
3 * 1/3 = 3/3 = 1.....so N is ur multiplicative inverse

Ok, I can see only a) to c)
a) Lucy spent the most time reading.
b) 20 minutes.
c) 22 minutes.
Step-by-step explanation:
Reason for b):

1 hour = 60 minutes
4 hours = ?
4 × 60 = 240 minutes.
Homework is 30°
Total in the pie chart is 360° so:
30/360 × 240 mins = 20 mins
Answer is Zac spent 20 minutes to do his homework.
Reason for c):
Watching TV:
Zac: 135°
Lucy: 102°
Zac:
135/360 × 240 minutes = 90 minutes
Lucy:

To find how many minutes Zac spent watching TV than Lucy:
90 minutes - 68 minutes = 22 minutes.

Answer:
C
Step-by-step explanation:
The book at store A is $13.
5% tax means you pay 5 cents extra per dollar.
13*5= 65.
So so far your total is $13.65
The shipping fee is $3
$3+$13.65= $16.65
The book at store B is 15% off, with no extra charge
%15 of $19 is 2.85.
19-2.85 is 16.15
