OCEAN FACT #1\u00a0<\/span>\u00a0 Over \u00be of our planet is covered by oceans<\/strong><\/span><\/p>\n

Math fun facts:<\/strong><\/span><\/p>\n

~ As a percentage, \u00be is 75%
\n~ As a decimal, \u00be is 0.75
\n~ As money, 75 cents
\n~ As a fraction, \u00be can also be written as:\u00a0 6\/8,\u00a0\u00a0 9\/12,\u00a0\u00a0 12\/16,\u00a0\u00a0\u00a0\u00a0\u00a0 15\/20,\u00a0\u00a0 18\/24,\u00a0\u00a0 21\/28,\u00a0\u00a0 24\/32,\u00a0\u00a0 27\/36,\u00a0\u00a0 30\/40\u00a0 <\/span><\/p>\n

We call these equivalent fractions.\u00a0 This means that they are all worth the same value <\/strong>– even though they look different!<\/span><\/p>\n

How did we find them?\u00a0 We multiplied the top number (numerator) by two and then we did the same to the bottom number (denominator) and got 6\/8.\u00a0 Then we multiplied the numerator by three and did the same to the denominator and got 9\/12.\u00a0 We went on with this pattern 10 times.\u00a0 Finally, we discovered that if we took the zero off 30\/40 it is the same as \u00be!<\/span><\/p>\n
