Given:
4 groups of ___ tenths is 1.6.
To find:
The value for the blank.
Solution:
Let the unknown value be x.
4 groups of x tenths is 1.6.
[tex]4x=1.6[/tex]
Divide both sides by 4.
[tex]\dfrac{4x}{4}=\dfrac{1.6}{4}[/tex]
[tex]x=0.4[/tex]
So, 4 groups of 0.4 tenths is 1.6.
Therefore, the required answer for the blank is 0.4.
