Understanding TENTHS

How would you say the following number? $\frac{3}{10}$  

• Ten thirds

• Three tens

• Ten threes

• Three tenths

Answer explanation

You would say the numerator as "three" and the denominator as "tenths" so all together it would be "three tenths".

How would you say the following number?

 $0.4$  

• zero point four

• four tenths

• four tens

• four

Answer explanation

Zero point four is an accurate description of what the number LOOKS LIKE but does not tell its value!  Saying "four tenths" not only tells what place the 4 is in but also, how much that 4 is WORTH!

• $\frac{16}{20}$

• Eight tenths

• Sixteen twentieths

• $\frac{8}{10}$

• $0.8$

Answer explanation

Sixteen twentieths is not correct because the question asks for TENTHS instead of TWENTIETHS.

If you draw all the dots then separate them into 10 groups or TENTHS, you can see that 8 of those 10 groups are green!

Which EQUATION could be used to represent the picture?

• $\frac{7}{10}$

• $0.7\ =\ 0.3\ +\ 0.4\$

• $\frac{4}{10}\ +\ \frac{3}{10}\ =\ \frac{7}{10}$

• $4\ +\ 3\ =\ 7$

• $0.7$

Answer explanation

$\frac{7}{10}$ or $0.7$ cannot be correct because the question is asking for an equation!

• $10\ +\ 10\ +\ 2\ =\ 22$

• $9\ +\ 7\ +\ 6\ =\ 22$

• $2.2\ =\ 0.9\ +\ 0.7\ +\ 0.6$

• $\frac{9}{10}\ +\ \frac{7}{10}\ +\ \frac{6}{10}\ =\ 2\frac{1}{5}$

• $\frac{6}{10}\ +\ \frac{9}{10}\ +\ \frac{7}{10}\ =\ \frac{22}{10}$

Answer explanation

The top two are only wrong because they are not showing any fractions! Whaddaya think this whole thing was about anyway?
