Q3

  1. 1. © mathsheuristics  After that, she cut the other string into equal parts of length 1.2m and to each part she tied 5 small balloons as in Figure 2. Jane had two strings of the same length. She cut one string into equal parts of length 90cm and to each part she tied 2 big balloons as in Figure 1. When she finished tying, she counted that there were 105 more small balloons than big balloons. How many balloons were there altogether? Length for each big balloon  90 ÷ 2 =45 1
  2. 2. © mathsheuristics  After that, she cut the other string into equal parts of length 1.2m and to each part she tied 5 small balloons as in Figure 2. Jane had two strings of the same length. She cut one string into equal parts of length 90cm and to each part she tied 2 big balloons as in Figure 1. When she finished tying, she counted that there were 105 more small balloons than big balloons. How many balloons were there altogether? Length for each big balloon  90 ÷ 2 =45 Length for each small balloon  120 ÷ 5 =24 1
  3. 3. © mathsheuristics  After that, she cut the other string into equal parts of length 1.2m and to each part she tied 5 small balloons as in Figure 2. Jane had two strings of the same length. She cut one string into equal parts of length 90cm and to each part she tied 2 big balloons as in Figure 1. When she finished tying, she counted that there were 105 more small balloons than big balloons. How many balloons were there altogether? Length for each big balloon  90 ÷ 2 =45 Length for each small balloon  120 ÷ 5 =24 1 2 Total Length Length 1u + 105 1u Number Small Balloon Big balloon
