amuhibPost authorHalimah,

Excellent. Well done for going back and checking your work!

Tamanna0.42+0.3=0.45

0.28+0.32=0.6

amuhibPost authorTamanna,

What question is this?

AzrinQuestion 1

a) 0.3 + 0.2 = 0.5

b) 0.2 + 0.1 + 0.2 =0.5

amuhibPost authorAzrin,

It’s correct!

AzrinQuestion 2

a)0.42+0.3

First convert the numbers.

0.3=0.30

0.42+0.30=0.72

b)0.28+0.32=0.60

0.60=0.6

amuhibPost authorAzrin,

Q2 – Both correct! Well done.

N4Y33SH41.0.5

2.0.5

amuhibPost authorNeed to write down your name.

Also, remember to say the question number and if it is …a) … b) …c), etc

N4Y33SH41.0.45

2.0.6

amuhibPost authorNeed to write down your name.

Also, remember to say the question number and if it is …a) … b) …c), etc

AzrinQuestion 4

First convert the litres.

Eva =1/4 of a litre is 0.25 L

Mo=0.3

Whitney= 1/10 of a litre is 0.1

0.3+0.1=0.4

Then do 0.25+0.3+0.4

0.25+0.3+0.4=0.25+0.30+0.40

0.25+0.30+0.40=0.25+0.70

0.25+0.70=0.95

The answer is 0.95

amuhibPost authorAzrin,

Great answer + working out.

Is that in litres or ml?

That’s right too.

Mo has used number bonds to 10 (which is not correct).

Amaara) 0.3 + 0.2 = 0.5

All correct! Except …. See below.

Question 3, answer should be a decimal.

Question 4 – double check.

Question 6 c) – double check.

Tamannab) 7 hundredths + 34 hundredths = 41hundreths

amuhibPost authorTamanna,

Answer should be in decimals.

TamannaQu3

A. 1.65

amuhibPost authorTamanna,

Double check answer.

Tamanna1.65 is question number 4,sorry😅

amuhibPost authorTamanna,

Doesn’t look right. Try again and write your answer in a number sentence.

TamannaQuestion:4

Eva drinks a quarter of a litre of water.

Mo drinks 0.3 litres of water.

Whitney drinks a tenth of a litre more water than Mo.

How much water do Eva, Mo and Whitney drink altogether?

My working-out

0.25+0.01+0.3+0.3=0.86

I know I got question number 4 before wrong but now I re did it

amuhibPost authorTamanna,

Very good attempt.

You have four numbers in your number sentence. Can you say who each number relates to.

E.g:

Eva –

Mo –

Whitney –

TamannaQU:5

0.97

0.11

0.75

Im not sure about the last question

amuhibPost authorTamanna,

I don’t think that’s correct.

Try again and write in a number sentence.
