51 is 33 1/3 of what number?

nevsk [136]

Answer:

$\boxed{\frac{153}{100}\:\:Or\:\:1.53}$

Step-by-step explanation:

Let the number be $n$ .

Then,

$33\frac{1}{3} \tmes n=51$

This implies that;

$\frac{100}{3} n=51$

We multiply both sides by $\frac{3}{100}$ to obtain;

$\frac{3}{100} \times \frac{100}{3}n=\frac{3}{100} \times 51$

$\Rightarrow n=\frac{3}{100} \times 51$

$\Rightarrow n=\frac{153}{100}$

$\Rightarrow n=1.53$

Write 12 ten thousands, 8 thousands,14 hundreds, 7 ones in standard form

Cloud [144]

The correct answer is: 
129,407.

Explanation: 
12 ten-thousands = 12*10000=120,000.
8 thousands = 8*1000=8000;
this gives us 120,000+8,000=128,000.

14 hundreds = 14*100=1400;
this gives us 128,000+1,400=129,400.

7 ones = 7*1=7;
this gives us 129,400+7=129,407.
