3 When you look at the pattern of the number 2 Remainder 0 1 2 3 4 5 6 7
pairs, the first numbers increase by adding 2 Finger Index Thumb Index Middle Ring Little Ring Middle
and the second numbers increase by multiplying Finger Finger Finger Finger Finger Finger Finger
by 2. Therefore, the first number of the seventh
number pair is 9 2 2 13, and the second 3 326 8 40 r6
number is 48 2 2 192.
4 The remainder is 6 when divided by 8, therefore
(13, 192) the ring finger will be used.
4 The numerators and denominators have different Problem solving
number patterns. 1 From numbers 1 to 6, the positions of the

patterns, the fractions that come next to 19 are
16 , 22 , 29 , and the fraction 29 of index 8 is
