1. Mrs Tofa is travelling to Australia. She intends to buy cookies for her students in Room 7. A packet of cookies has 12 cookies in it. If Mrs Tofa wants to give her 31 students 3 cookies each, how many packets does she have to buy?
First I will times 31 and 3 so 31 x 3=93. Next I will divide 93 and 12 so 93÷12=7.75 and to round it us to the nearest 1 so it equals to 8 soMrs Tofa will need 8 packets and the students will have 7.75 percent of the cookies and Mrs Tofa will have the other 25 percent
2. Mrs Tala goes shopping every Tuesday with her friends. On each Tuesday she spends around $97. If Mrs Tala shops every Tuesday for three months, how much money would she have spent?
4 weeks in 1 month so she spends $97x4= $388 a month so four months will be $97x12 but since march has five Tuesdays so it will be $97 times 13 so
$97x13=$1261
Mrs Tala spends $1261 in three months
