# Year 4 Maths Task- Monday 23rd March

**Tenths and Hundreths**

Read the questions carefully and remember to **number your answers and write them in the reply. **

You might need to work out on paper and then write it in your reply. If you have a printer, you could print it out and write your answers on there first.

This activity should take around an hour.

c. 5 tenths is equivalent t0 50 hunderedths and half

4. This is incorrect because he is used the first square to make the next column.

Great understanding of hundredths and tenths Bella

b. ½

c. 70/100

d.34/100

2.a 4 full rows =40

b. 6 full colloms =60

d. 2 full rows and 5 squares =25

e. 3 full colloms and 8 squares =38

3. a 4 tenths is equivalent to 50 hundredths

b. 70 hundredths is equivalent to 7 tenths

Great job Maisie!

1: a = 1/5, b = 1/2, c= 7/10 d= 17/50

2: a= 4/10, b= 6/10, c= 13/100, d= 1/4, e = 38/100

3: a: 40/100, b= 7/10, c= 50/100 or 1/2

4: Dexter is not correct. When he coloured in his column he had already coloured in one square for a row. Correct answer was 19/100

5: 1 to 5 have 23 squares, 6 doesn’t

6: a= 3/100, b= 4/10, c= 39/100, d= 0/100

7: Both are correct

5/10 + 23/100

4/10 + 33/100

3/10 + 43/100

2/10 + 53/100

1/10 + 63/100

Fantastic job on your maths Owen, working out equivalent fractions as well which is great.

e)3 full columns and 8 squares=38/100

3.

a)4 tenths is equivalent to= 4 hundredths

b)70 hundredths is equivalent to=7 tenths

c)5 tenths is equivalent to=5 hundredths or 1 hudredths

4.

yes/ he’s correct because 2times10=20 so 2 tenths

5.

4 correct=23/100

6.

a)23/100-2/10+21/100

d) 25/100= 1/4

e) 38/100

3 a) 40 hundredths

b) 7 tenths

c) 50 hundredths

4) He is incorrect. A row and a column will always cover one square together.

5) All except last one (number 6).

6a) 3/100

b) 39/100

c) 4/10

d) 0/100

b. 50/100=1/2

c. 70/100=7/10

d. 34/100

2.

a. 4 full rows = 40/100=4/10

c. 13 squares= 13/100

d. 2 full rows and 5 squares =25/100=1/4

e. 3 full columns and 8 squares = 38/100

3.

A. 4 tenths is equivalent to 40 hundredths

b. 70 hundredths is equivalent to 7 tenths.

c. 5 tenths is equivalent to 50 hundredths and 1half

4.

This is incorrect. 1 column and 1 row will make 19 squares, not 20.

5.

A,B,C,D and E.

6.

a. 3/100

b. 40/100

c. 39/100

d. 0/100

7.

Both are right.

73/100=50/100+20/100+3/100=1/2+2/10+3/100

73/100=4/10+33/100

Well done, Alex! I can see you’ve read the questions carefully.

5) all but last

6)

a) 3/100

b) 4/10

c)39/100

d)0/100
