Round number to nearest hundred 1,427 as 1,420. 68,136 as 68,130. 271,308 as 271,300. 7,593,656 as 7,594,000 right?

xenn [34]

Normally to round a number to the nearest hundred you want to go to the hundreds column for example:
1427
1...thousand, 4...hundred, 2...tenth, and 7... ones so this one would be 1400
68136=68100 and so on.... hope this helps

Rhion sat maths and English test

Sauron [17]

Answer:

Rhion did better in maths test.

Step-by-step explanation:

Given that:

Rhion scored 14 out of 17.

We will find percentage and then compare them.

Percentage = $\frac{Score}{Total\ marks}*100$

Percentage = $\frac{14}{17}*100$

Percentage = 82.35%

Rhion scored 31 out of 39.

Percentage = $\frac{31}{39}*100$

Percentage = 79.48

On comparing,

82.35 > 79.48

Hence,

Rhion did better in maths test.
