Question

I want the answers with step by step explanation​

Answer 1

Answer:

a) 459

Step-by-step explanation:

306÷12 =25.5

18×25.5 = 459

Answer 2

1. 12 ice-creams cost= 306 rupees

   cost of 1 ice-cream = 306 / 12 = 25.5

   18 ice-creams cost = 25.5* 18 = 459 rupees.

2. the length of an adult's toothbrush = 16.3 cm.

   the length of a child's toothbrush =  12.8 cm.

               =  16.3 - 12.8= 3.5cm.

so, the child's toothbrush is 3.5 cm shorter than an adult's toothbrush.

3. monday= 127.7 km

   tuesday = 208.5 km

   wednesday = 94.6 km

all together= 127.7 + 208.5 + 94.6 = 430.8 km.

so, neeta's father drove all together = 430.8 km.

4. Megha spend on bus fare everyday = 14.75 rupees

  total she spent in 15 days = 14.75 *15= 221.25.

so, megha spent in 15 days = 221.25 rupees.

5. team a scored = 97.2

   team b scored = 95.8

 by comparing we can say that team A scores more points and won the quiz.   97.2 - 95.8 = 1.4

   so, team A scores 1.4 points more than team B.

                         Hope it helps you and am sorry for the late answer cause i had already answered but the power cut. so again from first, I typed cause am using monitor. If there is a power cut i always face problems like this!
