Answer:
1:5
Step-by-step explanation:
find the LCF
<em>multiples </em><em>of </em><em>2</em><em>0</em><em>:</em><em> </em><em>1</em><em>,</em><em> </em><em>2</em><em>,</em><em> </em><em>4</em><em>,</em><em> </em><em>5</em><em>,</em><em> </em><em>1</em><em>0</em><em>,</em><em> </em><em>2</em><em>0</em>
<em>multiples </em><em>of </em><em>4</em><em>:</em><em> </em><em>1</em><em>,</em><em> </em><em>2</em><em> </em><em>4</em>
the lcf is <em>4</em>
20 ÷ 4=
5
4 ÷ 4=
1
the original ratio would be 4:20
