Answer:

1. A nutritionist poured 0.70 liter of honey into 0.14 liter plastic cups. How many plastic cups could be filled?

$\small{ \tt \red{GIVEN:}}$

$\small{ \tt \purple{0.70= \:Liter\: of\: honey.}}$

$\small{ \tt \purple{0.14\: =Liter\:of\: plastic\: cups.}}$

$\small{ \tt \red{SOLVING:}}$

$\small{ \tt \purple{0.7\div0.14}}$

Convert the decimal number to whole number.
0.7 = 70
0.14 = 14

$\small{ \tt \purple{\frac{70}{14}=5 }}$

${\large{nderline{\boxed{\sf{\green{Answer:5\:plastic \:cups \:can\:be \:filled.}}}}}}$

2. A rectangular rice field is 0.04 kilometer wide and has an area of 0.80 square kilometer. Find the length of the field.

$\small{ \tt \red{GIVEN:}}$

$\small{ \tt \purple{0.04\:km=Width\:of\:rectangular \:rice \:field.}}$

$\small{ \tt \purple{0.80\:km=Area\:of\:rectangular \:rice \:field.}}$

$\small{ \tt \red{SOLVING:}}$

$\small{ \tt \purple{0.04\div0.80}}$

Convert the decimal number to whole number.
0.4 = 4

0.80 = 80

$\small{ \tt \purple{\frac{80}{4}=20 }}$

${\large{nderline{\boxed{\sf{\green{Answer:20\:km\:the\:length\:of\:the\:field.}}}}}}$
