Maths, oceans apart

22 x 63=

Half 22 = 11

11 x 63 = 693

693 x 2 = 1386

34 x 48=

Half 34 = 17

17 x 48 = 816

716 x 2 = 1632

54 x 36=

Half 54 = 28

27 x 36 = 972

972 x 2 = 1944

Maths problem

This is one of the difficult problems that I've solved.

The five children in the Wipere family are Mihi, Sam, Rawiri, Tiere, Whitu. At Christmas, each child buys a $5 present fore each of the other children. How much is spent in total by all the children?

4x5=20

20x5=100

So there is only one child that is buying a Christmas present for all 4 of them. So he is spending 5$ each for each child. He won't buy a Christmas present for himself. That will equal to 20$, 20$ x 5 = 100$

Maths for today

Today for Maths we've learnt to put fractions into decimals. We've received fractions such as tenths, hundredth and thousandth.

Here are the equation and the answer that I've done:

Tenths:
9/10 = 0.9
10/10= 1

Hundredths:
60/100 = 0.60
72/100 = 0.72
42/100 = 0.42
98/100 = 0.98

Thousandths:
56/1000 = 0.056
560/1000 = 0.560
648/1000 = 0.648
976/1000 = 0.976

Here is the spear works that I've done:

0.56 = 56/100
0.72 = 72/100
0.156 =156/100

Problem solving 1

This maths problem is a bit difficult for me, but I got the towards the end.

Last week maths! ➕➖✖➗

A car uses 10 litres of fuel to go 100 kilometres.

How many will it need for 450 kilometres?

So 10x10=100 KM

10x45=450

Answer: 45

Different kind of strategy 450/10=45

Hamish and his brother eat 2 pieces of toasts each for breakfast, and his sister eats 1. If hamish has had 8 pieces so far this week, how many have the three of them eaten altogether?

Answer : 24

3x8=24

So if it was 2x8=16

But it is 3x8 which equals 24

Josh, ani, and philip have enough food to last 9 people for 5 days.

How long should the food last the 3 friends?

So 9 people and 5 days with enough foods

So 9/3=3 & 3x5=15 Days

This is what we just solved out but their was more equation than this but we just solved out the one we knew and this is all we got. Me, Vainikolo and George have been working on a equation each and we gave it our best.

1.5kg+1.5kg=3kg
So Mrs Tofa has 9 kg left. 
Because:
12kg-3kg=9kg

Mrs Tofa carry on weight is 9kg

Mrs Tofa would of just took her lollies and left the other one in the rubbish. 

So:
7kg+1.5=8.05

Answer 8.05

My Maths strategy!

For today Mrs Tofa ask us who want to do the strategy we have done for a family dinner that Roimata is organising. 

Here is my Strategy.

174x4=

100x4=400
70x4=280
4x4=16

174x5=

100+400=500

70+140+140=350

4x5=20

500+350+20=880

174x3=

Double of 100=200

200+100=300

70x3=210

It the same as 7x3=21

4x3=12

Answer is: 522
