Amber

Hello!

Mr Warbrick

9:52

Good morning Amber!

millie

9:54

why did it say Ella and Ava come on the chat

Mr Warbrick

9:55

That must be Miss Dawber sending a message to her class

Olivia

10:04

I’m a bit stuck on Q30

Mr Warbrick

10:05

This one is tricky. Let's start with CCCCC. If it = 30, what must C be?

Chelsea🐢

10:05

I need help with 28

Mr Warbrick

10:05

You need to start by adding the 3 amounts together.

Olivia

10:06

Mr Warbrick

10:06

Good!

If DDBAC is the smallest number, what is D likely to be?

Chelsea🐢

10:06

I got 283,947

Mr Warbrick

10:07

And rounded to the nearest 10,000, that is?

Olivia

10:07

5???

Mr Warbrick

10:07

They can only be 2, 4, 6 or 8

Chelsea🐢

10:07

200,000

Mr Warbrick

10:07

That's hundred thousand, not ten thousand

Olivia

10:07

Oh 4

Mr Warbrick

10:07

Is that the smallest?

Olivia

10:08

No 2!

Mr Warbrick

10:08

Right, so C = 6, D = 2. Use that to work out B. BDBCD = 18

Chelsea🐢

10:09

Oh 20,000?

10:10

284,000

Mr Warbrick

10:11

Not quite, that's the nearest 1000. It would be either 280,000 or 290,000. Which is it closest to?

Chelsea🐢

10:11

280,000

Mr Warbrick

10:11

Good

Olivia

10:13

On Q30, how do I work out what A is and what B is?

Mr Warbrick

10:13

We know that BDBCD = 18. You worked out that D = 2 and C = 6 so that does B equal in that?

Ben

10:13

I need help on the last Q

Mr Warbrick

10:13

This is what I'm working with Olivia on too, so we'll go through it together. See just above

Olivia

10:14

Is B equal to 8?

Mr Warbrick

10:15

No, use BDBCD = 18 to help. There's two Ds so we can take out 4, then there is a C so we take out another 6. That means we're taking 10 in total leaving....

Olivia

10:16

Leaving 8 and 4 so A must be one and B must be one

Mr Warbrick

10:16

No, just focus on the BDBCD = 18. We can work out which is which.

Mr Warbrick

10:16

If we take out the Ds and the Cs then we're left with BB = 8

So B = ?

Ben

10:16

is b 4
