Rambunctius Ratios

WALT: Use our knowledge of place value to solve multiplication problems
   Rambunctious Ratios
            We are learning to use multiplication and division to solve proportion and ratios problems.
Multiplication and Division Practice.
Work these problems out in your mind and discuss your strategies with your group. Show a couple of strategies below, but the rest of the questions can just be answered
  1. 29 x 20 = 580                      2. 33 x 15 =495 3.   76 x 24 = 1824 4.   65 x 17 =1105
       
      5.    72 x 15 =1080 6.   33 x 16 =528 7.   34 x 31 = 528 8.   42 x 26 =1092
      9.   90 ÷ 30 =3             10. 280 ÷ 40  =5            11. 300 ÷ 12 =25 12.   625 ÷ 25 =25


Word problem of the week:
For every 8 girls in a school, there are 12 boys. If there are 60 students in the school, how many girls and boys are there in the school? 24 girls 36 boys




Wicked word problems! 
 
Solve these problems. Write down your strategies:
  1. Jermaine has 120 lollies to share between some  friends. How many lollies would each friend get if there were 8 altogether? What if there were 16 or 24 people?
120÷8=15
120÷16=7.5
120÷24=5
  1. It takes 3 minutes to hang out 12 items of clothing. How long will it take to hang out 36 items?
12x3=36 clothing
3x3=9 minutes
  1. A pancake recipe calls for 3 cups of flour and 2 eggs. Marika is going to make several batches to bring to the garage sale. If she wants to use 9 eggs, how many cups of flour will she use?
  1. At the pools, one lifeguard is required for every 25 people.If there are 150 people booked to swim, how many lifeguards need to be working?
  2. 150÷25=6
  1. The pools also say that one adult can only look after two children under 5. If Pt England Kids are going swimming and they are taking 30 children, how many adults will they need?
  2. 30÷2=15
  3. 15 adults 30
  1. If the ratio is 2:8 then it is also ?:56
          2 adults to 8 children  14 adults to 56 children

    Hi Kahurangi,

    Well done for solving these problems! You have handled these multiplication and ratio problems really well. Keep thinking of the connection between multiplication and ratio as we discuss these ideas tomorrow.
